I'm guessing you have stealth orbitals. It seams if you have this skill, one energy array around an outpost or colony will effectively wipe out 500+ ships. Either that or our server is falling apart. I just had a solar system claimed, flew off toward my next target and all the planets in the system at once declared that I had claimed the planets, and reverted over to somebody else. Only problem is there was nobody else on at the time and no ships showed up before,during,or after the attack. Now if this had been a high point player that was playing at the moment I took his system I would have attributed it to quick thinking and maybe stealth ships, but this was a low point player that doesn't seem to have been playing in awhile. Go figure.
